2026 model release notes

Release date	Release
23.3.2026	Extended reanalysis and enhanced wind data: We have upgraded Wind Speed/Direction sources to ERA5 Land to ensure higher consistency for historical and TMY datasets. Optimized delivery and model availability: We have synchronized operational model management with satellite calculation times, enabling earlier access to Himawari and IODC data and reducing the overall availability delay for Monitor and nowcast data. Localized timezone resolution: Relative date parameters (e.g., forecastFromDay, DAY-1) are now resolved using the request’s timeZone, standardizing logic across Push and API services with a UTC fallback.
19.3.2026	Improved data processing: We have introduced new corrections for IODC data processing, mitigating reflections from existing solar power plants (India, UAE).
10.2.2026	Improved Forecast blending for Europe: We have implemented an updated blending scheme for forecast services covering the European territory. By incorporating ICON and IFS ensemble models into our processing chain, we have enhanced the reliability and consistency of forecast data across the region.
